I totally agree with the OP. I didn't have a problem with Dwight at first but as times goes on I find him more and more annoying. And I think he is really overrated ; he is great defensively, don't get me wrong, but his offense is non existent and he isn't a clutch player or a player that worries me the least offensively (I'm more worried when Gortat is on the court actually).
His "always smiling" attitude doesn't bother me that much (I mean, it's all good for us after all, I don't care he is a true "killer" or not) but his constant whining to the refs and his arrogant statements/attitude is annoying. His ridiculous interview last Sunday was just pathetic, he tried to be funny but it was just awful and embarrassing for him.
I don't like the fact that he calls himself Superman. I found his little show at the SDC funny, with his costume, etc, but to go as far as doing a Clark Kent/Superman interview with himself... wow.
I also dislike his attitude when he loses, he gets dirty and tries to play the "shocked" card.
